Fabrication of porous carbon nanofibers and their application as anode materials forrechargeable lithium-ion batteries

Abstract

Porous carbon nanofibers were prepared by the electrospinning of a bicomponent polymersolution, followed by thermal treatments under different atmospheres. The surfacemorphology, thermal properties, and crystalline features of these nanofibers werecharacterized using various analytic techniques, and it was found that they were formedwith turbostratically disordered graphene sheets and had small pores and largesurface areas. The unique structure of these porous carbon nanofibers resulted ingood electrochemical performance such as high reversible capacity and good cyclestability when they were used as anodes for rechargeable lithium-ion batteries.
